Description

ノズル掛けNozzle hook
　本発明は、水素充填装置において、水素充填ノズルが掛けられるノズル掛けに関する。 The present invention relates to a nozzle hook on which a hydrogen filling nozzle is hung in a hydrogen filling apparatus.
　水素ステーション等に設定されている水素充填装置は、充填ホースの先端に設けられた充填ノズルを水素充填装置のノズル掛けから外し、充填すべき車両の充填口に接続してその車両の水素タンクに水素を充填している。ノズル掛けに充填ノズルを掛けるには、例えば、充填ノズルの下端を深さ５０ｍｍ程度のフックに垂直に差し込んだ後、充填ノズルの上端をヒンジ状の蓋部品で固定していた。 The hydrogen filling device set in the hydrogen station or the like removes the filling nozzle provided at the tip of the filling hose from the nozzle hook of the hydrogen filling device and connects it to the filling port of the vehicle to be filled to the hydrogen tank of the vehicle. Filled with hydrogen. In order to hang the filling nozzle on the nozzle hook, for example, the lower end of the filling nozzle is vertically inserted into a hook having a depth of about 50 mm, and then the upper end of the filling nozzle is fixed with a hinge-shaped lid component.
　一方、車両の水素タンクに高圧の水素ガス、例えば７０ＭＰａの水素ガスを急速に充填しようとすると、断熱圧縮となり、車両の水素タンク内の温度が上昇する。このため、水素ガスを予め冷却して充填するプレクール充填と呼ばれる方法が実施されている。 On the other hand, when a high-pressure hydrogen gas, for example, 70 MPa hydrogen gas, is rapidly filled in the hydrogen tank of the vehicle, adiabatic compression occurs, and the temperature in the hydrogen tank of the vehicle rises. For this reason, a method called precool filling in which hydrogen gas is cooled and filled in advance has been implemented.
　上記従来のノズル掛けは、フックと蓋部品が別部材からなるため、これらの製造誤差及び取付誤差によって充填ノズルのノズル掛けへの掛かり具合が変化し、充填ノズルがノズル掛けから脱落する懸念があった。 In the above conventional nozzle hook, since the hook and lid parts are made of separate members, there is a concern that the filling nozzle will be hooked on the nozzle hook due to these manufacturing and mounting errors, and the filling nozzle will fall off the nozzle hook. It was.
　また、充填ノズルをノズル掛けに掛けるには、フックへの差し込みと、蓋部品による固定の二段階の動作が必要となるため、より容易かつ迅速に充填ノズルをノズル掛けに掛けることが望まれていた。 In addition, in order to hang the filling nozzle on the nozzle hook, it is necessary to perform a two-step operation of inserting into the hook and fixing with the lid part, so it is desired to hang the filling nozzle on the nozzle hook more easily and quickly. It was.
　さらに、従来のノズル掛けには、充填ノズルを保持する上下の部材の間に、充填ノズルを除くと片手分の隙間しか残っていないため、充填ノズルの掛け外しを片手で行わなければならず、充填者の負担が大きかった。 Furthermore, in the conventional nozzle hook, only the gap for one hand remains between the upper and lower members holding the filling nozzle except for the filling nozzle, so the filling nozzle must be detached with one hand, The burden on the filler was great.
　また、上記プレクール充填により、車両の充填口と接続される充填ノズルが冷却され、レバー等の可動部又は吐出管等の固定部が凍結して車両の充填口から充填ノズルが外れなかったり、次回の充填時に車両の充填口と接続できないおそれもあった。 In addition, the pre-cool filling cools the filling nozzle connected to the filling port of the vehicle, the movable part such as the lever or the fixed part such as the discharge pipe freezes, and the filling nozzle does not come off from the filling port of the vehicle. There was also a possibility that it could not be connected to the filling port of the vehicle when filling.
　そこで、本発明は上記従来の問題点に鑑みてなされたものであって、充填ノズルの掛け外しを容易に、迅速かつ確実に行うことができ、プレクール充填にも対応したノズル掛けを提供することを目的とする。 Accordingly, the present invention has been made in view of the above-described conventional problems, and can provide a nozzle hook that can easily and quickly detach / fill a filling nozzle and that can be used for precool filling. With the goal.
　上記目的を達成するため、本発明のノズル掛けは、一端に水素を吐出する吐出管と、他端に握り部を有する充填ノズルを掛けるためのノズル掛けであって、前記充填ノズルの吐出管を保持する上部と、該上部に相対向し、前記充填ノズルの握り部を保持する下部と、前記上部と前記下部とを繋ぐ中間部とを備えたノズル掛けであって、前記下部は、前記充填ノズルの前記握り部を不動状態で係止する固定係止部を備え、前記上部は、前記充填ノズルの前記吐出管に当接し、前記吐出管を可動状態で係止する可動係止部を備えることを特徴とする。 In order to achieve the above object, a nozzle hook of the present invention is a nozzle hook for hanging a discharge pipe for discharging hydrogen at one end and a filling nozzle having a grip portion at the other end, the discharge pipe of the filling nozzle being A nozzle hook provided with a holding upper part, a lower part facing the upper part and holding a grip part of the filling nozzle, and an intermediate part connecting the upper part and the lower part, wherein the lower part is the filling part A fixed locking portion that locks the grip portion of the nozzle in an immobile state is provided, and the upper portion includes a movable locking portion that contacts the discharge pipe of the filling nozzle and locks the discharge pipe in a movable state. It is characterized by that.
　本発明のノズル掛けによれば、上部、下部及び中間部が一部材からなるため、これらの製造誤差及び取付誤差が生じることがなく、充填ノズルとノズル掛けとの間の寸法誤差を極めて小さくすることができる。これにより、ノズル掛けからの充填ノズルの脱落等を確実に防止することができる。また、充填ノズルを固定係止部と可動係止部との間に配するだけで充填ノズルを両係止部で保持することができるため、ワンタッチで充填ノズルをノズル掛けに掛けることができる。 According to the nozzle hook of the present invention, since the upper part, the lower part, and the intermediate part are made of one member, these manufacturing errors and mounting errors do not occur, and the dimensional error between the filling nozzle and the nozzle hook is extremely small. be able to. Thereby, it is possible to reliably prevent the filling nozzle from falling off the nozzle hook. Further, since the filling nozzle can be held by both the locking portions only by arranging the filling nozzle between the fixed locking portion and the movable locking portion, the charging nozzle can be hung on the nozzle hook with one touch.
　上記ノズル掛けにおいて、前記可動係止部は、前記充填ノズルが該ノズル掛けに掛けられている際に前記吐出管を下方に付勢する付勢手段を備えることができる。これにより、ノズル掛けからの充填ノズルの脱落をより確実に防止することができる。 In the nozzle hook, the movable locking portion may include biasing means for biasing the discharge pipe downward when the filling nozzle is hooked on the nozzle hook. Thereby, dropping of the filling nozzle from the nozzle hook can be more reliably prevented.
　また、前記可動係止部を、下方に向かって突出する球状に形成すると共に、中心部にガス噴出口を設けることができる。これにより、吐出管の端部が球状に凹むように形成された充填ノズルのノズル掛けからの脱落をより確実に防止すると共に、噴出口から噴出するガス（圧縮空気、不活性ガス）によってプレクール充填等により凍結した水滴等を除去することができる。また、前記付勢手段によって吐出管を下方に付勢しながらガスを吐出することで、所定の部位に漏れを生じることなくガスを噴射することができる。 Further, the movable locking portion can be formed in a spherical shape protruding downward, and a gas outlet can be provided in the center. As a result, it is possible to more reliably prevent the filling nozzle formed so that the end of the discharge pipe is recessed in a spherical shape from falling off the nozzle hook, and precool filling with gas (compressed air, inert gas) ejected from the ejection port. It is possible to remove frozen water droplets and the like. Further, by discharging the gas while urging the discharge pipe downward by the urging means, it is possible to inject the gas without causing leakage at a predetermined portion.
　さらに、前記充填ノズルが該ノズル掛けに掛けられている際に、前記中間部と前記充填ノズルの側面との間に所定の大きさ以上の隙間が形成されるように構成することができ、これによって例えば、ユーザが充填ノズルを両手で把持した状態で充填ノズルの掛け外しを行うことができる。 Furthermore, when the filling nozzle is hung on the nozzle hook, a gap of a predetermined size or more can be formed between the intermediate portion and the side surface of the filling nozzle.

　次に、本発明を実施するための形態について、図面を参照しながら詳細に説明する。 Next, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
　図１は、本発明に係るノズル掛けを備えたガス充填装置の一例を示し、このガス充填装置１０の正面中央部に本発明に係るノズル掛け１が設けられる。同図は、充填ホース１３の先端部に設けられた充填ノズル１１がノズル掛け１に掛けられている状態を示している。 FIG. 1 shows an example of a gas filling apparatus provided with a nozzle hook according to the present invention, and the nozzle hook 1 according to the present invention is provided at the front center portion of the gas filling apparatus 10. The figure shows a state where a filling nozzle 11 provided at the tip of the filling hose 13 is hung on the nozzle hook 1.
　ノズル掛け１は、図２及び図３に示すように、大別して、充填ノズル１１の吐出管１１ａを保持する上部２と、充填ノズル１１の握り部１１ｂを保持する下部３と、上部２と下部３とを繋ぐ中間部４とを備える。 As shown in FIGS. 2 and 3, the nozzle hook 1 is roughly divided into an upper part 2 that holds the discharge pipe 11 a of the filling nozzle 11, a lower part 3 that holds the grip part 11 b of the filling nozzle 11, and an upper part 2 and a lower part. 3 and an intermediate portion 4 that connects the three.
　上部２は、充填ノズル１１の吐出管１１ａを係止する可動係止部５を備え、この可動係止部５は、上下方向に延設される軸部材５ａと、軸部材５ａの表面上を摺動可能で、下方に向かって球状に突出する本体５ｂと、本体５ｂを下方向に付勢するばね５ｃとで構成される。また、上部２には、充填ノズル１１の吐出管１１ａから排出される微量の水素が滞留するため、滞留した水素を抜くための貫通孔２ａが穿設される。 The upper portion 2 includes a movable locking portion 5 that locks the discharge pipe 11a of the filling nozzle 11. The movable locking portion 5 includes a shaft member 5a extending in the vertical direction and a surface of the shaft member 5a. The main body 5b is slidable and protrudes spherically downward, and includes a spring 5c that urges the main body 5b downward. Further, since a small amount of hydrogen discharged from the discharge pipe 11a of the filling nozzle 11 stays in the upper portion 2, a through hole 2a for removing the staying hydrogen is formed.
　軸部材５ａ及び本体５ｂは、各々中心部に貫通孔５ｅ、５ｆが形成されると共に、これらの貫通孔５ｅ、５ｆが圧縮空気搬送管９の内部と連通している。これにより、圧縮空気源から圧縮空気搬送管９及び軸部材５ａを介して本体５ｂの噴出口５ｄから吐出管１１ａに向かって圧縮空気（ドライガス）を噴射し、吐出管１１ａに付着する水滴や、凍結物、ごみを除去することができる。ここで、可動係止部５の本体５ｂが下方に向かって凸球状であると共に、吐出管１１ａの先端が凹球状に形成されているため、噴出口５ｄが吐出管１１ａの凹部内に位置し、吐出管１１ａに付着する凍結物等を効率よく除去することができる。 The shaft member 5a and the main body 5b are formed with through holes 5e and 5f at the center, respectively, and these through holes 5e and 5f communicate with the inside of the compressed air conveyance tube 9. Thereby, compressed air (dry gas) is jetted from the jet outlet 5d of the main body 5b toward the discharge pipe 11a through the compressed air conveying pipe 9 and the shaft member 5a from the compressed air source. Can remove frozen, garbage. Here, the main body 5b of the movable locking portion 5 has a convex spherical shape downward, and the tip of the discharge pipe 11a is formed in a concave spherical shape, so that the jet outlet 5d is positioned in the concave portion of the discharge pipe 11a. Moreover, the frozen substance etc. adhering to the discharge pipe 11a can be removed efficiently.
　下部３は、充填ノズル１１の握り部１１ｂの下端に接続される充填ホース１３を避けるために下面視Ｕ字状に形成される凹部６を備え、凹部６に握り部１１ｂの下端を係止する段部７が形成されている。段部７は、例えば１０ｍｍ程度の高さを有し、段部７には、握り部１１ｂの下端で押圧されてＯＮになるノズルスイッチ８が設けられている。 The lower part 3 includes a recess 6 formed in a U-shape when viewed from the bottom in order to avoid the filling hose 13 connected to the lower end of the grip part 11 b of the filling nozzle 11, and the lower end of the grip part 11 b is locked to the recess 6. A stepped portion 7 is formed. The step portion 7 has a height of about 10 mm, for example, and the step portion 7 is provided with a nozzle switch 8 that is pressed by the lower end of the grip portion 11b and turned ON.
　中間部４は、充填ノズル１１を両手で把持した状態で充填ノズル１１の掛け外しを行うための空間４ａを形成しながら、上部２と下部３を繋いでいる。 The intermediate part 4 connects the upper part 2 and the lower part 3 while forming a space 4a for detaching the filling nozzle 11 while holding the filling nozzle 11 with both hands.
　次に、上記構成を有するノズル掛け１に充填ノズル１１を掛ける動作について、図４を参照しながら説明する。尚、図３及び図４において、ガス充填者の手及び充填ノズル１１の下端部に接続される充填ホース１３の図示を省略している。 Next, the operation of applying the filling nozzle 11 to the nozzle holder 1 having the above configuration will be described with reference to FIG. 3 and 4, the illustration of the filling hose 13 connected to the hand of the gas filler and the lower end of the filling nozzle 11 is omitted.
　ガス充填者は、充填ノズル１１の握り部１１ｂを両手で握った状態で、図４（ａ）に示すように、充填ノズル１１を傾けながら吐出管１１ａをノズル掛け１の中間部４の手前の空間に挿入する。次に、その状態から充填ノズル１１を上昇させ、図４（ｂ）に示すように、吐出管１１ａで可動係止部５を上方に押し込むようにして吐出管１１ａを上部２の下方に挿入する。 As shown in FIG. 4A, the gas filling person holds the discharge pipe 11 a in front of the intermediate portion 4 of the nozzle hook 1 while tilting the filling nozzle 11 while holding the grip portion 11 b of the filling nozzle 11 with both hands. Insert into the space. Next, the filling nozzle 11 is raised from that state, and the discharge pipe 11a is inserted below the upper portion 2 so as to push the movable locking portion 5 upward with the discharge pipe 11a as shown in FIG. 4 (b). .
　吐出管１１ａで可動係止部５を上方に押し込んだ状態で、充填ノズル１１の握り部１１ｂを前方（図面では左方向）に移動させると、図４（ｃ）に示す状態になる。この状態では、まだ充填ノズル１１の握り部１１ｂが下部３の凹部６に収納されておらず、段部７の上面に載置された状態である。そこで、さらに握り部１１ｂを前方に移動させ、図３に示すように、充填ノズル１１の握り部１１ｂの下端部を凹部６に収容した状態で段部７によって係止する。 When the gripping portion 11b of the filling nozzle 11 is moved forward (leftward in the drawing) while the movable locking portion 5 is pushed upward by the discharge pipe 11a, the state shown in FIG. 4C is obtained. In this state, the grip portion 11 b of the filling nozzle 11 is not yet housed in the concave portion 6 of the lower portion 3 and is placed on the upper surface of the step portion 7. Therefore, the grip portion 11b is further moved forward, and as shown in FIG. 3, the lower end portion of the grip portion 11b of the filling nozzle 11 is locked by the stepped portion 7 while being accommodated in the recess 6.
　握り部１１ｂを段部７に係止した後は、作業者が握り部１１ｂから手を離すだけで、可動係止部５の本体５ｂがばね５ｃで下方に付勢されるので、図３に示すように、吐出管１１ａが可動係止部５の本体５ｂに係止され、充填ノズル１が下方に付勢された状態でノズル掛け１に保持される。 After the grip portion 11b is locked to the stepped portion 7, the main body 5b of the movable lock portion 5 is urged downward by the spring 5c simply by releasing the hand from the grip portion 11b. As shown, the discharge pipe 11a is locked to the main body 5b of the movable locking portion 5, and the filling nozzle 1 is held by the nozzle hook 1 while being biased downward.
　以上のように、本実施の形態によれば、上部２、下部３及び中間部４が一部材からなり、これらの製造誤差及び取付誤差が生じることがなく、充填ノズル１１とノズル掛け１との間の寸法誤差を極めて小さくすることができる。これにより、ノズル掛け１からの充填ノズル１１の脱落等を確実に防止することができる。 As described above, according to the present embodiment, the upper portion 2, the lower portion 3 and the intermediate portion 4 are made of a single member, and these manufacturing errors and mounting errors do not occur. The dimensional error between them can be made extremely small. Thereby, dropping of the filling nozzle 11 from the nozzle hook 1 can be reliably prevented.
　また、充填ノズル１１の握り部１１ｂの段部７への係止と、吐出管１１ａの可動係止部５への係止をワンタッチで行うことができる。 Further, the gripping portion 11b of the filling nozzle 11 can be locked to the stepped portion 7 and the discharge tube 11a can be locked to the movable locking portion 5 with one touch.
　さらに、ばね５ｃで充填ノズル１１を下方へ付勢することにより、段部７の高さが１０ｍｍ程度でもノズル掛け１からの充填ノズル１１の脱落を防止することができるため、充填者の負担を軽減することができる。 Furthermore, by urging the filling nozzle 11 downward with the spring 5c, it is possible to prevent the filling nozzle 11 from dropping off from the nozzle hook 1 even when the height of the stepped portion 7 is about 10 mm. Can be reduced.
　一方、上述のようにプレクール充填等を行うと、充填ノズル１１が凍結するおそれがあるため、図３及び図４に示すように、圧縮空気搬送管９から供給される圧縮空気を可動係止部５の噴出口５ｄから充填ノズル１１に噴射する必要がある。この圧縮空気噴射動作について図３及び図５を参照しながら詳細に説明する。 On the other hand, if the precool filling or the like is performed as described above, the filling nozzle 11 may be frozen. Therefore, as shown in FIGS. 3 and 4, the compressed air supplied from the compressed air transport pipe 9 is moved to the movable locking portion. It is necessary to inject to the filling nozzle 11 from the 5 jet nozzles 5d. This compressed air injection operation will be described in detail with reference to FIGS.
　ＰＯＳ端末等の上位機器からノズル掛け１に充填許可信号が入力されると（ステップＳ１；Ｙｅｓ）、可動係止部５の噴出口５ｄから充填ノズル１１に圧縮空気（エア）を噴射し（ステップＳ２）、ノズルスイッチ８がオンになると（ステップＳ３；Ｙｅｓ）、圧縮空気の噴射を停止する（ステップＳ４）。 When a filling permission signal is input to the nozzle hook 1 from a host device such as a POS terminal (step S1; Yes), compressed air (air) is jetted from the outlet 5d of the movable locking portion 5 to the filling nozzle 11 (step). S2) When the nozzle switch 8 is turned on (step S3; Yes), the compressed air injection is stopped (step S4).
　ステップＳ１～ステップＳ４により、充填ノズル１１をノズル掛け１から外れ易くすると共に、充填ノズル１１の吐出管１１ａを車両の充填口に接続し易くする。 In steps S1 to S4, the filling nozzle 11 is easily detached from the nozzle hook 1, and the discharge pipe 11a of the filling nozzle 11 is easily connected to the filling port of the vehicle.
　充填が終了してノズルスイッチ８がオフになると（ステップＳ５；Ｙｅｓ）、噴出口５ｄから充填ノズル１１に圧縮空気を噴射し（ステップＳ６）、圧縮空気を噴射してからの時間Ｔが所定時間ｔ１（例えば１０秒）に達したら（ステップＳ７；Ｙｅｓ）、圧縮空気の噴射を停止する（ステップＳ８）。 When the filling is completed and the nozzle switch 8 is turned off (step S5; Yes), the compressed air is injected from the outlet 5d to the filling nozzle 11 (step S6), and the time T after the compressed air is injected is a predetermined time. When t1 (for example, 10 seconds) is reached (step S7; Yes), the compressed air injection is stopped (step S8).
　ステップＳ５～ステップＳ８により、次回の充填に備えて、充填ノズル１１に付着する凍結した水滴等を除去することができる。 By steps S5 to S8, it is possible to remove frozen water droplets and the like adhering to the filling nozzle 11 in preparation for the next filling.
　次に、本発明に係るノズル掛けの第２の実施の形態について、図６を参照しながら説明する。 Next, a second embodiment of the nozzle hook according to the present invention will be described with reference to FIG.
　このノズル掛け２１は、上部２２に凹部２２ｂを形成した点で前述のノズル掛け１と異なる。この凹部２２ｂが存在することにより、ガス充填者は、充填ノズル１１（図４参照）を傾けながら吐出管１１ａをノズル掛け２１の中間部４の手前の空間に挿入し易くなり、その後、充填ノズル１１を上昇させて吐出管１１ａを上部２２の下方に挿入し易くなるため、ノズル掛け１と比較して、充填ノズル１１（図３等参照）をノズル掛け２１に掛け易くすることができる。また、上部２２には、滞留した水素を抜くための貫通孔２２ａが穿設される。尚、図６において、ノズル掛け１と同様の構成要素については、同一の参照番号を付して説明を省略する。 The nozzle hook 21 is different from the nozzle hook 1 described above in that a recess 22b is formed in the upper portion 22. The presence of the recess 22b makes it easier for the gas filling person to insert the discharge pipe 11a into the space before the intermediate portion 4 of the nozzle hook 21 while tilting the filling nozzle 11 (see FIG. 4). 11 becomes easy to insert the discharge pipe 11 a below the upper portion 22, so that the filling nozzle 11 (see FIG. 3 and the like) can be easily hung on the nozzle hanger 21 as compared with the nozzle hanger 1. The upper portion 22 is provided with a through-hole 22a for removing the accumulated hydrogen. In FIG. 6, the same components as those of the nozzle hook 1 are denoted by the same reference numerals, and description thereof is omitted.
　上記実施の形態では、可動係止部５に本体５ｂを下方向に付勢する付勢手段としてばね５ｃを設けたが、必ずしもばね５ｃを設ける必要はなく、本体５ｂを下方向に付勢しないで充填ノズル１１を可動係止部５と凹部６及び段部７との間で保持することもできる。 In the above embodiment, the spring 5c is provided as the biasing means for biasing the main body 5b downward in the movable locking portion 5, but the spring 5c is not necessarily provided, and the main body 5b is not biased downward. Thus, the filling nozzle 11 can also be held between the movable locking portion 5 and the recess 6 and step 7.
　また、可動係止部５の位置や形状等も、図示例以外のものとすることもでき、充填ノズル１１の握り部１１ｂを不動状態で係止する下部３の固定係止部と、充填ノズル１１の吐出管１１ａに当接し、吐出管１１ａを可動状態で係止する可動係止部を備える構成であれば、他の構成を採用することもできる。 Also, the position, shape, etc. of the movable locking portion 5 can be other than the illustrated example. The fixed locking portion of the lower portion 3 that locks the grip portion 11b of the filling nozzle 11 in a stationary state, and the filling nozzle Other configurations may be employed as long as the configuration includes a movable locking portion that contacts the 11 discharge tubes 11a and locks the discharge tubes 11a in a movable state.
　さらに、ノズルスイッチ８をノズル掛け１の下部３に設けたが、上部２に設けることもでき、可動係止部５に設けることもできる。また、噴出口５ｄからは、圧縮空気（ドライガス）に代えて不活性ガスを噴射することもできる。 Furthermore, although the nozzle switch 8 is provided in the lower part 3 of the nozzle hook 1, it can also be provided in the upper part 2 and can also be provided in the movable locking part 5. Moreover, it can replace with compressed air (dry gas) from the jet nozzle 5d, and can also inject an inert gas.
